CAN HEADING AND BEADING MACHINE.

l SPECIFICATION forming part Of 4Letters. Patent N0. 648,280, dated April 24, 1900.

Application ledll'uly 3, 1899. Serial No. 722,681. (No model.)

Be it known that I, CHARLES B. MODON- ALD, residing at Chicago, county of Cook, and State of Illinois, have invented a certain new and useful Improvement in Can Heading and Beading Machines, of which the following is a specication. v

My invention relates to an improvement in that class of can-manufacturing machinery known as can-heading machines and is designed to produce a machine that will simultaneously place a head upon one end of the hollow cylinder constituting the body of the can while it simultaneously forms a bead on said cylinder near its opposite end, the

said beadbeing designed to,` cooperate with the removable cap ordinarily employed with such cans.

I have shown my improvement as applied to the type of machine shown in my Patent No. 594,547, dated November 30, 1897 3 but it will be understood that the broad idea of my invention might be employed in other types of machines.

Referring to the two sheets of drawings, in which the same letters of reference are used to designate identical parts in all the views, Figure l is an end elevation of the complete machine, except that a portion of the framework is shown in section and the feed and discharge chutes are omitted. Fig. 2 is a vertical section, on an enlarged scale, through the center of the heading and beading devices proper; and Fig. 3 is a side elevation of the completed can, a portion thereof being in section to show the construction of the bead.

In setting out my invention I will first describe the general construction of the complete machine in the particulars wherein it is the same as that shown in my prior patent referred to, and to which reference is made for a fuller illustration and description of the parts not specifically concerned with the present improvement.

Referring to the drawings by letter, A A represent the framework of the machine. This framework, near its center, is provided with two upright standards A A. A Suitable mechanism,`such as a chute, `'(not shown,) is provided for carrying the can-bodies B to the operating parts ofthe machine, and they are taken from this chute one by one by the feedwheel C, which may be briefly described as provided with a series of recesses C', which are approximately semicircular in outline and of a somewhat larger radius than the canbody which they receive. Each of these recesses is provided with the rollers C3 and C7, with which the can-,bodies directly contact, .so that they are held in the feed-wheel by their three points of contact with the roller Cs and the two rollers C7, respectively, so that while thus securely held they are nevertheless perfectly free to revolve as necessary in the operation of the machine. The feed-wheel C is shown as partially inclosed by the casing C9, and the casing C9, in`which it is mounted upon the shaft D, journaled in bearings A2, formed in the standards A' of the framework. On the shaftD at one end is keyed the ratchetwheel D, provided on its outer surface with the ratchet-teeth d, with which coperate the spring-actuated plunger-pawl D3, secured in the upper end of the crank D2, which is loosely mounted on the shaft and has connected thereto the rod D4, by which the crank D2 is reciprocated to intermittently advance the feed-wheel. Upon the other end of the shaft D is keyed the friction-pulley D7, surrounded by a friction-belt DS, by which the momentum of the machine may be overcome.

Upon each side of the feed-wheel C and concen tricwith each recess C at the lowest point to which it is brought by the rotation of said feed-Wheel is mounted a shaft F in bearings As and A4, formed in the standards A' of the frame. The said shaft F is not only free to revolve in these bearings, but is also adapted to reciprocate longitudinally therein. Adj acent to the bearing A3 the shaft F carries acollarf, secured thereto, so as to move longitudinally with the shaft and to permit the shaft to revolve loosely in said collar. Between this collar and the remaining bearing a coiled spring f surrounds the shaft. The shaft is thus held in its normal position with the collar f abutting against the bearing A3. The shaft is revolved by the pulley F', which is keyed to said shaft, but is free to slide thereon, so as to allow longitudinal movement of the shaft without interfering with its movement of revolution. The outer end of the shaft F fits into a cap f3, which is pivotally secured by means of the ears f6 to the lever G, which IOO vided at its lowerl end with an antifri'ctionroller g',which coperates with the cam-flange g2, secured upon the face of the lwheel G7, to be subsequently referred to. A coiled spring f5 surrounds the end of the shaft F, between the cap f5 and the belt-pulley F', so as to provide a certain degree of resiliency in the inward movement of the shaft F, as caused by the inward movement of the cap f5 under the actuation of the cam-wheel G7. The two camwheelsrG?, onejon either side of the machine, are rigidly secured to the shaft G', mounted in suitable bearings vin the framework and driven by the power applied to the machine. It will readily be seen that as the shaft G rotates and the cam-flange g2 contacts with lthe antifriction-roller g', the lever G will be swun'g'about its bearing g, so as to force the 4shaft F inward against the resistance of the spring f5 and f'.

V `Theinner end o f the right-hand shaft F zc arries a circular hood F2. This hoodcomlprises the disk-shaped back F5 and an annular inWardly-projectin g Wall F4, within which Vthere is thus formed a circular `recess F5. lhelhood F2 is loosely mounted on the shaft F, so as not to partake of the revolution of the'shaft, but so as to move backward and forward with the same, being retained between the collar FX and the chuck F7, herein subsequently described. The guide-rods F5 (one of-which'isshown in'Fig. -1 secured at one end to the hood) extend through guide- Yapertures formed inthe framework near the bearings A2 and TA4 of the shaft F and permit the reciprocation of the hood F2, while preventing its rotation. On the extreme end -ofthe shaft F within the hood F2 is mounted "a disk-'shaped chuck F7, adapted to `revolve with the shaft within the rear portion of the circular recess F5 of the hood. The working y surface of the chuck is provided with an auf nular rim F5. The outer portion of the cir- 'cular recess F5 of the hood, somewhat larger than the inner portion, flares outwardly, as at f 8. The inner end of'this aring concave portion constitutes a shoulder f2. Behind this shoulder there is thus formed a groove flo. In the upperV side of the hood an opening fm lis formed through thefwall F4 of the hood, adapted to permit the droppingr of a can-head into the groove flo. In the lower side of thehood there is formed a second openingf12, through the wall F4, adapted to permit the crimping-roll later described to contact with the lower edge of the cam-head when seated in the groove fw. On the righthand side of the feed-wheel C is located the Ainclined feedchute H, down which pass the bottoms forming the lower heads of the cans. The chute H terminates over the hood F2 and I is-provided with an opening in its bottom whichregisters with the opening fn whenthe said opening into the g'rbve flo. Ana'u'tomatic feeding device, which need not here be described, is providedk to insure the regular feeding of a single head tothe hood at each time that the-hood comes to its normal outer position.

The can head or bottom I is disk-shaped and has its edge bent inward to form an annular lip I'. A short distance inside of the said lip is formed an annular ridge I2 on the inside surface of the head, producing a corresponding annular depression 13 on-the outside surface of the said head. On th inner surface of the head there is thus formed between the lips I and the ridge I2 an annular groove I4, which registers with the edge of t-he can-body.

The shaft. G", heretofore described, carries a pair of cam-wheels J, identical in form with each other, each being. provided 4along one portion of its periphery with a raised camsurface, the limits of which on the other side of the wheel are indicated by the dotted lines at J'. l

In the framework of the machine, separated by a distance substantially equal to the depth of the can to be headed, are located twouprightspindles K, each of vwhichisadapted to reciprocate-in gu'ideways K', formed in said framework. Each spindle is provided with an upper head K2 and a lower head K3 onfopposite sides of the guideways K'. v Between the lower head Kand theframework A a helical expanding spring K4 surrounds the spindle and holds the same in anormal downward position, with the head K2 abutting against the framework A. The lower head K3 isV provided with two perforated ears k, in

- which is mounted a roller 7c', adapted to travel around the periphery of the cam-wheel J. The `upper heads K2,Icarried by the spindle, are provided with the ears 7a2, between which, on the right-hand one, is mounted a crimping-roll K5, with a beveled surface 705.

vIn the framework A, between thetwo crimping-roll spindles K, is mounted a short standard L, in which is journaled a roller L', the upper surface of the said roller being adapted 'to contact with the can-body carried by the feeding-wheel when in position to be headed.

The construction hitherto explained is that of my prior patent, above referred to, and the dierence's embodying my present invention will now be described. f t

On the left-hand side of the machine, vinstead o'f employing the chute H, the hoods F2, and the chuck F7,I fasten on the extreme inner end of the shaft a chuck N, which is formed with the fiange N thereon, against the inner surface of which the end of the can -abuts when the shaft F has been advanced to its innermost position, as subsequently explained. At a suitable point on the cylindrical surface of the chuck N, I form the beading-ridge N2, which is a circular bead extending around the entire periphery of the chuck, and I preferably form ,a beveled sur- IOO IIO

face N3 on the inner yend of the chuck. Oo-

operating with this chuck, and especially with the beadingmidge N2, is the beading-roll O, which is mounted similarly to the crimpingroll K5, but which is formed with the beading-groove O' in register with and corresponding in size to the beading-ridge N2. On either side of this groove O' are the horizontal surfaces O2 and O3, which coperate with the corresponding horizontal surfaces N4 and N5 on the chuck N.

The operation of my improved machine is as follows: The can-bodies B' are taken up from the chute one by one in the recesses C of the feeding-wheel C, the said feed-wheel being given an intermittent motion through the ratchet-'wheel D and connecting mechanism. In time each such can-body is brought by the revolution of the feed-wheel to a position between the hood F2 and chuck F7 on one side and thechuckNontheotherside. Thehood F2contains a can-head I, fed into it automatically. The hood and chucks are in their outer or normal position. By the revolution of the camwheels G7 the hood and the chucks are brought toward each other upon opposite sides of the can-body,as shown particularlyin Fig. 2. lThe can-head I is retained in its groove f 10 by reason of the lip I' engaging with the shoulderfg, which forms the inner side of said groove. As the head in the hood approaches the body of the can the edge of the can-body fits into the annular groove I4, extending around the head. The annular rim F2 of the chuck F7 firs within the circular depression I2 of the head, while the chuck N enters the other end of the canbody until its iiange N5 is pressed firmly against it by the action of the springs, and thus the head and can-body are rapidly revolved by the revolution of the chucks, which the springs f5 press inward against the head and the can-body with a yielding pressure. The can-body is readily revolved by its mounting between the rollers C2, C7, and C7,of which there are three for each holder in the feedwheel, and the roller L', with which it comes in contact in this position. By the time that the chucks have been moved inward by the revolution of the cam-wheels G7 the raised surfaces J on the cam-wheels .I contact with the rollers k and force upward the crimpingroll K5 and the beading-roll O. The crimpingroll crimps down the lip I of the can-head I upon the can-body, the roll being revolved by contact with the revolving can-body. At the same time the upward pressure of the spring K4 causes the beading-groove O' to cooperate with beading-ridge N2 to form the bead B2 upon the can-body. The continued revolution of the cam-wheels J now permits the spindles and the crimping-roll and beading-roll to drop down to their normal position, and immediately thereafter the continued revolution of the cam-wheels G7 permits the hood and chucks to resume their normal outer position. This leaves the can-body with its headin the feed-wheel. The lip I' of the head, having been crimped down, no longer catches upon the shoulder f of the hood and allows the head which is crimped on the can-body to remain in position thereon while the chuck and hood are withdrawn from over it. The subsequent rotation of the wheel C brings thc can which had been headed and beaded to the point where it is discharged.,

While I have shown my invention as embodied in the form which I at present consider best adapted to carry out its objects and as applied to a machine built in accordance with my prior patent, it will be understood that it is capable'ofsome modications, as well as application to other machines, and that consequently I do not desire to be limited in the interpretation of the claims, except as may be necessitated by the state of the art.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

1. In a machine of the class described, the combination of the can-supporting member comprising a support in which the cau-body can rotate freely, with can-heading mechanism on-one side thereof and the can-beading mechanism on the other side thereof, said mechanisms being adapted to rotate the can and operate on it during said rotation, and means for operating both of said mechanisms simultaneously.
